To ZZ 'whom it may concern Be 1t known that we, FRANK llinmxos and Ronnn'r Ri .liinnxzimn citizens of the llnited :following is a full. clear, and exact description.

`This; invention relates to loading' machines adapted particularly for une in minesl where the head room is limited, and is o' the Lrieneral typeot' loadingv machine. constitutiiu; the Subject. matter of a companion applic tion Filed by ue: ot' even date herewith.

In the companion application relxrred to, l dieclosed a loading machine, which a truck and a loading' structure thereon comprising' a reciprocating" rain carevinga material conveying; element `in the iorm oi. ay shovel supported from the ram by `swinlgjing arms, `the ram being mounted for reciprocating' morement :ton wardly and rearwardly, and on ite loiwvard moven'ient cali-'singl the shovel to be loaded with material, and the SwingingM arma` being;` la-rraiiged so that when the ram. retracted shoiel back over the machine so that the material can he dumped in suitabley reeeivingy element at the rear thereof. ln said companion application a :single motor is prol.vided for reciprocating the rain and for swinging the arms and the shovel, the latter togetherg with the arms being swung upwardly andrearwardly while the rain 1S traveling rearwardly near the end o'l its rearward stroke, and the Shovel and arms are swung forwardly and downwardly durupwardly and rearwardly.

and arms to be :swung back over the machine within a given head room without requiring armeA oi the telescopic type.

rl`he invention may he further briefly summarized as consisting in certain uovcl details ol construction l(rnd combimxtions and arrangrementfs of parte which will be described in the sl'aeilication and Het forth in the appended claims.' p

ln the :uaonuiairving sheet of drawings, Fie'ure l is a side view ot the improved machine 'with the parte in the relative positions which they occupi' at the beginning' of the forward or filling stroke; Fig'. 2 is a top lplan 'view of the same; Fie'. l is a view similar to Figi. 1 on a reduced scale. showing the ram extended and 'the parts in the relative positionawhieh they occupy when the ram is :fully extendedA` this` view showing also by dotted lines, other positions oi the ram, shovel, and ot the shovel supportingT arms; Fig. 4 is a Al'rout view ol the machine; and

ligxili. a tra nnverse Sectional view substantialliY along the line .fi-f5 of Fig. 1.

The machine includes a wheeled trucklO on which are nuiunted the working parte: ol the machine, these being in thel'orm of a Siwan-Structure which can be turned about a vertical axis, the truck' being' in this case, provided with arc-shaped tracks 11. and the superstrueture with roller@` 12 which engage the tracks;` and are guided thereon. The body of the, Supereliructure iS in this case formed by a long horizontal c vlinder 1.3 of a fluid presSure motor which is about as long as the truck. This motor is adapted to reciprocate forwardly and rearwardly a ram composed of a front member 1l which is connected to the plunger 15 ot' the motor, and two side meml'ierev lli which exteiul rearwardly' along-"nido the cylinder lil, this ra'm' being; therefore substantially U-shaped. The side members 16 ot thel ram are formed in this case ot angles and plates including three angles 1G, 1 6 and 16 with inwardly turned flanges, and connected together by one or more plates 16d. ThiS ram and the parts supported therehl are leluiported and guided 'lor forward and rearward reciprocating movement-'hy rollers and tracks including two track bars 17, secured to opposite Side. of the cylinder 13, these track bars being engaged by upper and lower rollers 18 carried hiv the rear end of the ram and adapted to :..iw'ege the upper and lower faces the bars, and they are further Supported by for y'ardly disposed rollers 19 which are supported at the lower front.v portion of the cylinder 13 and are engaged by the ianges of the lower angles 1Ga ot' the ram.

The ram is adapted to reciprocate, that is to say, move forwardly and rearwardly a material n'ioving or loading element, here shown as a shovel 20, which is substantially triangular shaped and has an open front and a bottom plate which is the digging or scooping` part. This shovel Yis supported Jfrom the ram by swinging arms 21 which are connected to opposite sides of the bucket and which during the filling stroke otl the ram extend downwardly and forwardly from the latter and rest upon bumpers or stopsl 22 which are carried by brackets 23 secured to the trout side portions ot'the ram. These brackets can be adjusted to vary the iui'liuation of tilie arms during' the filling stroke, and in ordei that the shovel may be properly positioned with respect to the arms regardless ot' their inclination during the filling stroke, the shovel may be adjusted relative to thi arms. To accomplish this the arms are connected by pins oistiids 20a to the sides of' the shovel so that. the latter can he tilted or turned relative to the arms and can be fastened in any adjusted position by bolts :20h extending through arcshaped slots 20C oit' the arms, as shown' clearly in Fig. l.

In the` companion application previously referred to, these arms are swung, and at the lsame time they are given a rolling action by means of? gear segments which when the ram is retracted to a. certain point engage,A relatively stationary racks', all movements l beingr imparted by one motor and taking place during the movement ot' the ram either rearwardly or forwardly.

ln this case we obtain the same swingingv and rolling;` movements, but the latter can be givento the shovel independently of the movement ot' the ram, and by separate motive means. It will be seen, particularly by reference to Fig. l, that the. arms are pro- `vided at. their inner ends with gear segriiients 2l which engage, and are adapted to roll over vracks 25 which are carried by, and are arranged along the sides of the ram in the planes of the gear segments. The rolling and swinging movements are imparted to the arins'and shovel by a second motor, which as here shown, comprises a horizontal cylinder 2G, which is above the main cylinder13, and is considerably shorter than the latter. This cylinder 2G has at its opposite sides, laterally projecting flanges 27 which are secured to the upper rear portions ot the ram. and it is provided with a forwardly extending plunger and cross head Q9 (see Fig'. Lt) t0 which are connected I shaped links or straps 30 having forwarfJ rolle-rs 3l and rear rollers 32. traveling;` in long slots or gnideways of the ram, the shovel sup porting arms 21 being attached to the rear ends of these links, preterably'on the studs Ot the rear rollers 32, as shown in Fig. l.

Thus it will be seen that when the plunger 2S of the upper motor is shifted, the links 30 are moved forwardly or rearwardly as the case may be, with the rollers travelingalong the slot 33, and by reason ot the engagenient of the gear segments 24 with the racks 25,'the shovel and the arms are simultaneously given a movement ot rotation and a movement of translation, the arms andshovel swinging about the centers of the rollers 32. and at the saine time the centers o't these rollers travel in a straight line.

ln operation, with the parts in the positions shown in Fig. l, the ram is moved for vardly as far as desired, with the shovel in digging position, as shown, so as to till the shovel. Then the ram is retraetedand either just. before or after this rearward movement is terminated. the am of the upper motor is retracted, causing the shovel andthe arm 'supporting it to bel swung up over the machine and back to .the rear thereotl so that the contents of the shovel can be discharged into a dump car or other suitable receiving' element at the rear of the'machine. Then the shovel and shovel supporting arms are swung forwardly to the first position, after which the shovel is again filled and the operation is repeated.

Vith this mechanism the shovel can be swung trom a point in front of the machine,

back over the same, so as tofdischarge the beingmoved to shovel can be elevated immediately after beingfilled, so that as it is drawn rearward, material is not liable to tall trom the same, and inasmuch as the swinging movements ot the shovel and of its supporting arms' are not dependent upon the movement of the ram and are .not required to be given to the shovel and' arms while the ram still has lto pass through a portion of its movement, the

machine can be shortened somewhat over that in the companion application, and the shovel will clear the forward end of the ram as it is beine` swungr upwardly or down-y wardly with the relative short radius arms.

When the machine is beineV used in the manner above described. it. will, of course, be b aced or held against tipping or tilting Tate motor for; operating .Quid

moonen iorwzirclly when the rum is extended. This con be done by track anchors oi' clumps or by bracing the rear end of .the machine against the overhead ruine tin'iber'ing.

lt will be understood that strokes of voriable speed and length un be given to the nioving parte of the two fluid pressure znotors which are preferably air motors by' o suitable valve mechanism which is notI here loaded with nme'i'inl is swung" to dumping' position, the Shovel. supporting firms :are actuated so :is to lift 'the load :is well move it i'eaiwui'dly, the lifting effect oeingD dependent on the radius of the gem' Seg ments. The lifting and. rearward moving' actions can be varied to suit the cxigenoies of any particular cese by 'weaving the reluion of vthe length of the shovel suppowizing arms and. iie adios of foe geef Scginens.
